BOILER-BRACE.

SPECIFICATION forming part of Letters Patent No. 699,999, dated May 13,1902.

Application led November SO, 1901. Serial No. 84,229. (No model.)

To all whom it may concern:

Be it known that we, JOHN S. WORTH and CHARLES B. FAIEWEATHEE, citizensofv the United States, and residents of Coatesville, Pennsylvania,haveinvented certain Improvements in Boiler-Braces, of which the followingis a specification.

Our invention relates to certain improvements in braces forstrengthening boilers and other sheet iron or steel structures.`

The main object of our invention 'is to economically manufacture such abrace and provide sufficient metal at places where strength is needed,and yet make it of comparatively light material.

A further object of the invention is to separate the base of 'the brace,so as to allow an opening between the two feet for the-circulation ofWater, so that there will be com para-v tively little surface of theboiler-plate covered by the brace. -v

In the accompanying drawings, Figure 1 is a perspective view of ourfimproved brace. Fig. 2 is a side view. Fig. 3 is a View looking in thedirection of the arrow 3, Fig. 2. Fig. 4. is aview looking in thedirection of the arrow 4, Fig. 2. Fig.' 5 is arviewof the blank fromwhich the brace is made.

Referring inthe first instance to Fig. 5, A

is the'blank, cut, preferably,vfrom sheet-steel; and of the shape shownin the drawings, hav-'` ing a body portion a, a base portion d', and

a head portion a2.. Extending from each sidev of the head portion arewings a3, and extend-L ing from the base are portions b b, which;r

eventually form the feet oftheV brace. In the rst operation the blank Ais bent on the center line 0cm, so as to form theinclinedportionI A ofthe brace, and is then bent on the lines'- y fy, so as to form the feetb.

We separate the feetb h of the brace, so as to form a V-shaped passage dbetween the feet. The height of this passage is indicated by the dottedlines, Fig. 2. When the brace is secured to the shell of the boiler, thewater will freely circulate through this V-shaped passage, and thus'protect the'shell to a certain extent, as it is found to beobjectionable to cover the surface of the boilerwith a single plate,owing-to the fact that the boiler is liable to burn out at this point.

The head of the brace is iiattened out, as shown in the drawings,from-the point c, and the wings a3 are turned back upon the head portionof the brace, as indicated in Figs. l and 4, so as to give this headportion, which is perforated at e e, the strength desired.

The size of the brace may be varied and the shape slightlymodiliedwithout departing from the main feature of our invention.

It will be seen that we can make a very substantial and stiff brace ofcomparatively light material, Which can be readily secured in place inthe boiler and the brace strengthened where necessary, and, furthermore,a

rcomparatively small surface ofthe boilershell is covered by the feet'of the brace, as these feet are made as small as possible and aredivided by the channel, through which the Water can freely flow.

' We claim as our inventionl. As a new article of manufacture,aboilerbrace made of a single sheetof metal bent so as to form a bodyportionof double thickness, a head portion of double thickness connectedto the body portion by a single thickness of metaland having feet ofsingle thickness,

.substantially as described.

2. As a new article of manufacture, a boilerbrace made of a single sheetof metal bent so as to form an inclined body portion of doublethickness, a headportion, said head portion having wings bent upon thehead portion, and having feet spread apart and forming a channel,substantially as described.

3. As a new article of manufacture, a boilerbrace made of a singlesheetof metal having an inclined body portion of double thickness, ahead portion of doublefthickness and feet extending from each side oflthe base of the inclined portion, the base of-.theninclined portionbeing spread apart forming a V-shaped channel between the feet,substantially as described. f'

4. A blank for a boiler-brace consisting,r of naines to thisspecification in the presence of a single sheet of metal having a bodyportion two subscribing Witnesses. a, at head portion a2, wings a3projecting from JOHN S W-ORTH each side of the head. portion andportions 1 5 I) projecting at an angle froin the opposite CHARLES LFAIRWEATHILR end of the body portion, substantially :is defitnesseszscribed.
